<p>In an ion mobility separation device, there has been a problem that while arraying of separation electrodes or flow paths is subject to restrictions, finely setting a correction voltage causes an increase in correction voltage scanning time, resulting in a reduction of the throughput. The aforementioned problem can be solved by the following means, for example. That is, this ion mobility separation device is characterized in that at least one of a pair of plate electrodes includes a first electrode section of a first conductivity, a second electrode section of a second conductivity, and a third electrode section that is provided so as to be sandwiched between the first electrode section and the second electrode section and has a third conductivity smaller than the first conductivity and the second conductivity, the first electrode section, second electrode section, and third electrode section are arranged perpendicularly to a flow path, and a voltage control unit applies different direct-current voltages respectively to the first electrode section and the second electrode section.</p> |
